Title: Apparatus for determining the characteristic values associated with the presence of an obstacle in a guide for electromagnetic waves
IPC: G01R27/06
Filed: 1947-01-17
Abstract: 635,769. Electric tests. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Jan. 17, 1947, Nos. 1636 and 1637. Convention dates, Jan. 18, 1946, and July 6, 1946. [Class 37] [Also in Group XL (b)] Apparatus for determining the reflection coefficient of an obstacle in a wave-guide comprises two sections of wave-guide forming extensions of the guide containing the obstacle, a movable probe for detecting the electric field in one extension guide, a movable piston in the other extension guide, means for simultaneously moving the piston and the probe, and means for marking the positions of the piston and the probe. As shown, a movable probe 7 projects into an extension of a waveguide containing an obstacle 0. A movable piston 10 is provided in an extension of the other end of the guide. The probe 7, and piston 10 are coupled by means of a cable 11 and screw 9 to move in the same direction, or by cable 11 and screw 8 to move in opposite directions. The probe and piston are first moved together and two adjacent standing wave zeros marked. The probe is then moved midway between these zeros when the piston and probe will be equally spaced from the electric phase of symmetry of the obstacle. Screw 9 is now loosened and screw 8 tightened so that the piston 10 and probe 7 move symmetrically. The distance between two adjacent standing wave zeros, and the distance between the piston and probe when the latter is midway between the two zeros are now measured. The reflection coefficient of the obstacle may be determined from these measurements. A crystal or suitable detector is mounted on the carriage of the probe. In a modification (Fig. 3, not shown), the piston and probe are carried by members driven by two oppositely threaded screws. Adjustable shoes engaging one or other of the threaded rods enable the relative direction of movement of the piston and probe to be changed. Coarse adjustment is effected by means of a rotor and reversing clutch. In another embodiment (figs. 4-8, not shown), the probe carriage is provided with grooved wheels running in extensions of the sides of the wave-guides. The detector circuit is completed through the wheels which are pressed against the rails by adjustable springs.

Abstract: 539,976. Spindle arrangements for spinning frames. TRIGGS, W. W. (Saco-Lowell Shops). Jan. 26, 1940, No. 1639. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 2, 1940.] [Class 120 (ii)] A spindle arrangement for a spinning frame comprises a dead spindle having spaced bearings for supporting a driving sleeve and a base which supports the spindle and provides a fulcrum for the spindle while permitting universal swinging movement thereof but preventing radial movement of the spindle at the fulcrum ; damping means are provided adjacent the lower end of the spindle to damp the swinging movement non-elastically to enable the sleeve during operation to find a stable position of rotation. As shown the spindle 2 is pressed into the upper part of a non-rotatable bolster 3 supported in a base 4 secured to the spindle rail. The sleeve 8 is supported on the spindle by upper and lower sets of ball bearings 9, 10 and a bobbin, frictionally held on the sleeve, is supported by a whorl 12 thereon. The lower end of the bolster is supported on a shoulder 20 in the base 4 with a clearance between the bolster and the wall of the base so that the lower end of the bolster can move with comparative freedom on the shoulder 20 and lubricant introduced into the base through a hole 18 lubricates the shoulder and the lubricated surfaces provide the non-elastic damping action which allows the spindle to adjust itself automatically to the position necessary for smooth running. The bearings may be lubricated by oil introduced into the bore of an internally grooved cap 13, any surplus oil being caught in a stationary cap 14 and escaping through a hole 17 to the hole 18. The cup 14 fits over the extension 15 of the base and has its rim taking into an annular recess 16 in the whorl. The lower end of the bolster may be disposed in an oil well so that the spindle will be additionally damped and cushioned by the oil film between the outer peripheral surface at the bottom of the bolster and the inner peripheral surface of the spindle base. A weight may be mounted on the upper end of the cap 13 to improve the running at high speeds and in another form the bolster is short and has a flange resting on the extension 15 of the base so that the bolster and spindle are carried by the extension in which the bolster has a clearance while the end of the spindle extends with clearance into an oil well at the foot of the base 4 ; the sleeve is a tapered tube fitting over and secured to an upward extension of the whorl.

Title: Improvements in or relating to the electrolysis of liquids
IPC: C25B9/00
Filed: 1933-01-18
Abstract: 408,767. Electrolysis. HEUTSZ, J. B. VAN, 8, Jacob Hopstraat, The Hague. Jan. 18, 1933, No. 1706. Convention date, Nov. 19, 1932. [Class 41.] In the electrolysis of liquids for the production of gases, electrodes having the same external dimensions or projection surface (or substantially the same in the case of curved electrodes) but different effective areas are employed, the ratio of the effective areas being so chosen as to provide a maximum current density (referred to the projection surface) for a given applied voltage. By this means the decomposition voltage for a given electrolyser may be reduced. The effective area of an electrode may be reduced by perforations or increased by the provision of ribs. The effective area of a fabric electrode may be greater or less than that of a plane electrode according to the width of the meshes. Either the anode or the cathode may require the greater effective area according to the nature of the electrolyte and the electrode materials. The invention is applicable to the electrolysis of a 30 per cent caustic potash solution. Suitable ratios are given for the effective areas when electrodes of iron, nickel and V2A metal are employed.

Abstract: 1,176,711. Clutches. NICHIRO KOGYO K.K. 12 Jan., 1967, No. 1803/67. Headings F2C and F2L. [Also in Division B8] Torque transmitted from a member 36 (Fig. 4), through circumferentially arranged springs 57 to a member 50 causes axial movement of a member 35 keyed slidingly at 62 to the member 50. The members 36 and 35 engage one another through saw-teeth (58), (Fig. 3, not shown) so that the relative angular movement permitted by the springs 57 causes axial movement of the member 35 against a spring 59. In the binding machine (see Division B8) described, this movement is applied through a linkage (Fig. 7) to initiate the operation of a one-revolution clutch. The one-revolution clutch comprises a latch 72 (Fig. 6), pivoted at 73 to a normally stationary member 70 but allowed to rise, under the influence of a spring 75, when a stop 74 is removed, so that the latch engages dogs 68 on a rotating member 67 which in consequence drives the member 70. Towards the end of one revolution the stop 74 is returned by a cam 93 to the position in which it disengages the latch 72. A further cam 29 driven from the member 70 disconnects the drive to the torque-measuring device described above, so that the linkage is reset to the position in which it does not displace the stop 74.
